Congratulations are in order for Idris Elba and his girlfriend Naiyana Garth. The happy couple welcomed their first child together yesterday, a baby boy named Winston Elba!

The actor shared the exciting news, and a picture of the infant gripping his finger, with his Twitterfollowers. “My Son Winston Elba was born yesterday,” the 41-year-old “Luther” star wrote. He went on to described the birth as “truly amazing.”

We were first introduced to Idris’ lady love at the Golden Globes in January, where she made her debut among the eye candy’s die-hard American fans. She graced the red carpet rocking a mother-to-be glow and black gown by British maternity-wear designer Tiffany Rose. According to reports, Naiyana is British just like her boyfriend. She is described as “a London-based professional hair and make-up artist with extensive experience in Fashion, Film, special effects/prosthetics, Body Painting and Bridal.”
